The client now issues PUT /squad and the hub renders coins, record and the
squad roster. Three separate root causes, all verified live.
Squad blocker (the long-standing "client never sends PUT /squad"):
AddPlayerToSquad, GetSquads and SelectSquadById issue ZERO network requests
(pure local model reads/mutations, FutSquadServiceImpl vtable 0x180233ff0);
only SaveCurrentSquad writes, and it is unguarded. The client simply needed a
populated ACTIVE squad model, which arrives via the massinfo `squad` member.
No response of ours was ever being rejected.
userMassInfo is NOT required to be {}:
0x180174630 is a FLAT {userInfo, squad, settings, userData} body -- the old
"wrapper key is user" note was wrong, and the historical freeze was the
malformed squad member, not the envelope.
clubNameChangeAllowed must be false:
sending true advertises a club-rename flow whose UI model is never populated;
the client shows a naming prompt and dies confirming it (ACCESS_VIOLATION
reading 0x0 at FIFA17.exe+0x71b8651, 4/4 runs, no CardsDLL frame and no request
in flight). Isolated by a single-variable run; guarded by a contract check.
Endpoint/schema corrections found in live traffic, invisible to static analysis:
* GET ut/%s/squad/list is a real endpoint and must return {"squad":[...]},
not the active-squad object (the /list suffix is appended by the caller, so
it never appeared in the request table)
* PUT lands on ut/%s/squad/<id>, not a bare ut/%s/squad
* userInfo currencies are read as name/funds/finalFunds/active -- there is no
"value" key, so coins always rendered 0
* squad-list elements take STRING formation/squadType, not ints
* the CardsDLL script-API thunk<->name table was off by one (AddPlayerToSquad
is 0x18004aa70; 0x18004aff0 is GetPotentialChemistry_Club)
FUT_MASSINFO / FUT_USERINFO ladders keep every step of the bisect reproducible.
Contract suite 311 -> 358 checks. Tooling added: PyGhidra harness (Ghidra's
Java/OSGi script path is broken on this box), minidump reader, live code grabber.

OpenFUT
Offline Ultimate Team — like SPT, but for FIFA 23.
OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.
Repositories
| Repo | Purpose |

openfut-core |
Game-independent offline FUT backend |
openfut-bridge |
FIFA 23 integration layer + reverse-engineering proxy |

SQLite database
Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.
Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Running
# Start the offline backend
cd openfut-core
cargo run
# Start the proxy (for traffic capture / FIFA integration)
cd openfut-bridge
cargo run
Core listens on http://127.0.0.1:8080 by default.
Bridge listens on http://127.0.0.1:8443 by default.
Design Principles
- Offline-first. No EA account required. No internet connection needed.
- Single-player only. This is not a multiplayer server emulator.
- Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
- Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
- No copyrighted assets. No real player images, no EA trademarks in data files.
